The first fully supported ARM platform in coreboot is the Samsung XE303CE Chromebook ("snow"). It features an Exynos5250 SoC with a dual-core Cortex-A15 (ARMv7) processor. More info about the Exynos5250 is available here.

ARM SOCs with PCIe are now on the market for tablets, netbooks and servers. These systems can take advantage of coreboot's strength in properly configuring PCI, SAS, SATA and SCSI devices; fast boot times; and payload support.
